Hi
I am trying to locate information regarding a Thomas or William Dyson who was born in England but then emigrated to Australia (Tasmania) in the late 1800's. I am lead to believe that he held a Government post (Minister ?), anybody know where i can find out if this was indeed correct ?

He had a sister Edith b. 1870 (?) d. 1951 & she was married to Thomas Snowden (Architect) d. 1933 approx.

Any info appreciated

Thanks
